Thanks for the info. Its understandable why your D1H is better in shutter lag times and in autofocus. D1H is using CAM1300 while N80 is using CAM900 (same with the one that will be used with D100). Anyway, you pretty much answered my question already so performance of D100 will really be almost same as N80 and that if i want the AF speed and almost none shatter lag of F100 then i should go with D1X/H. Again thank you!
